Pac-10 stock rising with four bids

In this bracket, the Southeast matches up with the Southwest, the East with the West in the national semifinals.

With the addition of three at-large spots (increasing the field to 68 teams), there are now four play-in games, dubbed the "First Four." Two games will match the tournaments lowest seeds, Nos. 65 through 68, with the winners claiming a No. 16 seed. The other two games will feature the last four teams of the 37 at-large qualifiers, with the winners likely receiving No. 11 or 12 seeds.

The top-four seeds in each region, starting with the No. 1 seeds, receive geographic preference when possible. An imbalance in high seeds between regions (e.g. if more than two top-four seeds are closest to the same subregional location) may force a protected seed into a secondary location.

League winners (automatic qualifiers) are listed with their conference for clarity. Teams can be moved a seed line up or down to conform to bracketing rules. Auto bids in traditional one-bid leagues were determined by best RPI of league leaders.
